/**
 * @class Ext.form.Label
 * @extends Ext.Component

Produces a standalone `<label />` element which can be inserted into a form and be associated with a field
in that form using the {@link #forId} property.

**NOTE:** in most cases it will be more appropriate to use the {@link Ext.form.Labelable#fieldLabel fieldLabel}
and associated config properties ({@link Ext.form.Labelable#labelAlign}, {@link Ext.form.Labelable#labelWidth},
etc.) in field components themselves, as that allows labels to be uniformly sized throughout the form.
Ext.form.Label should only be used when your layout can not be achieved with the standard
{@link Ext.form.Labelable field layout}.

You will likely be associating the label with a field component that extends {@link Ext.form.field.Base}, so
you should make sure the {@link #forId} is set to the same value as the {@link Ext.form.field.Base#inputId inputId}
of that field.

The label's text can be set using either the {@link #text} or {@link #html} configuration properties; the
difference between the two is that the former will automatically escape HTML characters when rendering, while
the latter will not.

#Example usage:#

This example creates a Label after its associated Text field, an arrangement that cannot currently
be achieved using the standard Field layout's labelAlign.

    Ext.create('Ext.form.Panel', {
        title: 'Field with Label',
        width: 400,
        bodyPadding: 10,
        renderTo: Ext.getBody(),
        layout: {
            type: 'hbox',
            align: 'middle'
        },
        items: [{
            xtype: 'textfield',
            hideLabel: true,
            flex: 1
        }, {
            xtype: 'label',
            forId: 'myFieldId',
            text: 'My Awesome Field',
            margins: '0 0 0 10'
        }]
    });

 * @param {Ext.core.Element/String/Object} config The configuration options.
